A theoretical question on a known effect:
Suppose one were to make a Casimir-engine for the production of negative energy. If one placed said engine in a spinning centrifuge on the International Space Station, would the negative energy repel the centrifugal effect, and rise to the weightless...
There exist shapes of particular materials that self-propagate in vacuum due to the Casimir effect. Such an object would use vacuum polarization to accelerate relative to other, quasi-inertial objects. Does this absolute motion disagree with relativity, or might it relate to the blackbody...
This is a simple (and possibly not very bright) question:
We know that F=A/d^4 for the Casimir Force (~10^-7 N for two cm^2 plates).
Does the gravitational attraction between the masses of the plates not figure?
I once thought that this was not an EM effect as such or at least doesn't...
